AI Technical Summary

Technical Problem

In existing technologies, particle size detection after material crushing is done offline, which cannot provide real-time data feedback. Furthermore, manual sample preparation and detection are prone to large errors, affecting real-time adjustments to the crushing process and material utilization efficiency.

Method used

An online powder sampling and particle size detection device was designed, including a crushing device, a powder collecting device, a weighing, stirring and dispersing device, a dispersion tank and a testing device. The device enables automatic sampling and real-time detection of materials through a conveying pipeline, and coordinates the operation of each component using a control system.

Benefits of technology

It enables real-time detection of particle size after material crushing, reduces human error, and improves the real-time adjustment capability of the crushing process and the efficiency of material utilization.
